AMT/LLJ-YL flow converter controller is an impeller flow measurement instrument, high resolution large screen LCD display, provides instantaneous flow/cumulative flow/transmission/control, a variety of main parameters on the same screen display, the use and view is very convenient. The flow of liquid in the pipe impacts the turbine to create rotation, and the magnet on the turbine blade produces a measurement signal in the sensor as it rotates, which is proportional to the flow rate of the fluid. Through a correlation coefficient K corresponding to the diameter and material of each joint, the meter measures and calculates the current flow rate. Proven for a long time, the rotary flowmeter has reliable performance, easy installation, high output signal repetition, strong structure, and no or little maintenance. Flowmeter output sine wave frequency signal, can drive 3-5090 passive flow indicator. The dynamic flow rate measurement range is 0.3~6m/s to measure liquid flow at full pipe and low pressure system environments. There are many types of liquid material configurations for rotary flow meters, including PP or PVDF shells, which have excellent chemical resistance, so that the flow meter can be used to measure many corrosive liquids. The flowmeter can be inserted into a wide range of pipe diameters, the maximum size can reach DN900(36 "), Futech standard mounting types include tee, saddle, straight welded mounting parts, etc., to ensure the correct insertion depth of the flowmeter in the fluid. Suitable for clean water pipeline or low concentration chemical fluid, low viscosity fluid, non-trade settlement flow measurement and process control.
